Ziton ZR420 Radio Thermal Sensor

ZR420-1 Low Voltage Heat Sensor

Thermistor controlled Designed to provide heat detection on ZP3 systems, where the installation of hard wiring is not an option, the Ziton ZR420 wireless thermal sensor is a thermistor-controlled device, which responds to changes in its ambient temperature.

The Ziton ZR420 Radio Thermal Sensor unit is controlled directly from the main fire detection panel, via a loop wired radio interface module. This arrangement allows both wireless and hardwired devices to be seamlessly located on the same loop wiring. The Ziton ZR420 Radio Thermal Sensor provides a reliable response to fires in areas where environmental conditions may prohibit the use of smoke sensors.

EN54 Part 5 (grade 1) approvals The sensitivity of each ZR420-1 Low Voltage Heat Sensor is set by the main control panel and can be adjusted between four levels - from 58 ºC to 75ºC, either manually or on a timed basis. At sensitivity level two the Ziton ZR420 radio thermal sensor fully meets the requirements of European Standard EN54 Part 5 (grade 1) and is approved by several international approval bodies.

Installed as part of the ZP3 analogue addressable system, up to 127 devices can be connected to each of the control panel loops.

Each wireless device, controlled through the ZR470 loop interface is assigned its own IDENT address, with which the main control panel communicates, providing the same system facilities as directly wired devices.

Automatic calibration and self-test Temperature levels are continuously sensed by the unit and transmitted to the radio loop module, which in turn relays the data to the main control panel. Four levels of sensitivity can be set and calibration and self-test are carried out automatically. Removal or replacement of an incorrect sensing device is identified by the system and details displayed at the main control panel.

For ease of removal sensors plug into the ZR400 radio base by a simple twist and lock action. Bases are installed using a matching fixing plate. A site selectable option is provided to lock the sensor into its base. Once applied the Ziton ZR420 Radio Thermal Sensor can only be removed by means of a special tool.

  • No external aerials
  • Dual battery supply
  • Full device status monitoring - power sources, head removal and device tamper
  • Automatic sensitivity adjustment, alarm verification and self test
Model No ZR420-1
